Answer:
Speed
Explanation:
Speed is a scalar quantity, defined as the ratio between the distance covered and the time taken:
[tex]v=\frac{d}{t}[/tex]
where
d is the distance covered
t is the time taken
Speed is measured in meters/second (m/s).
It should be noted that speed is different from velocity: in fact, velocity is a vector quantity, whose magnitude is defined as
[tex]v=\frac{d}{t}[/tex]
where d is the displacement (not the distance), and it also has a direction, while speed does not have it.
